Python write_barcode Examples

Example #1

        self.assertTrue(res.valid)
        self.assertEqual(res.format, format)
        self.assertEqual(res.text, text)

Example #2

        self.assertTrue(res.valid)
        self.assertEqual(res.format, format)
        self.assertEqual(res.text, text)
        self.assertEqual(res.orientation, 0)
        self.assertEqual(res.position.topLeft.x, 4)

Example #3
